So I’ve got this configuration:
$ cat /etc/apt/apt.conf.d/99-phased-updates
# dont take part of phased updates
# Disable phased updates: https://people.canonical.com/~ubuntu-archive/phased-updates.html
# https://discourse.ubuntu.com/t/phased-updates-in-apt-in-21-04/20345
#
# To have all your machines phase the same, set the same string in this field
# If commented out, apt will use /etc/machine-id to seed the random number generator
#APT::Machine-ID "aaaabbbbccccddddeeeeffff";
#APT::Machine-ID "n0c0ffeen0deadbeef50l337";
# Always include phased updates (Default = 1)
APT::Get::Always-Include-Phased-Updates "false";
# Never include phased updates
APT::Get::Never-Include-Phased-Updates "true";
But sometimes, it fails, downgrading them manually, then retrying upgrade/dist-upgrade, doesn’t install them anymore, but initially they get installed anyways. Something is weird, but I can’t tell what.
The GUI for user update upgrades is not installed and removed.
